I am a 21 mtf crossdresser and have been dating this girl for about a week. I invited her over to my place to hang out and watch movies and I cooked for her. After a few drinks and other activities in the bedroom she wanted to take a shower and I showed her where my bathroom was and let her take one. I was cleaning the kitchen she she walked out of the bathroom holding a handful of my panties and two bras and demanded to know who they belonged to. In my tipsy panic I said they were my ex girlfriends that she never came back to get. She is very open and I want to tell her that I crossdress but I'm worried that if I do she will be angry I lied or freaked out by the fact that that was mine. Any ideas on how to handle this situation without causing damage to the relationship?
